A2 核心表达
Help
如何表达平时的习惯,客观真理,比如:太阳从东方升起
使用一般现在时态,即主语 + 动词原形(三单加 -s/es):The sun rises in the east.(第三人称单数变化规则:sh/ch/o/x 结尾加 -es)
如何表达正在进行的动作,比如:他们正在刷墙,现在正在下雨
使用现在进行时,即 am/is/are + 动词-ing:They are painting the wall. It's raining now.(注意:非动作动词如 know、like 通常不用于进行时态)
如何表达已经完成的过去动作或状态,比如:我去年去了上海,她昨天很开心
使用一般过去时,即动词的过去式形式:I visited Shanghai last year. She was happy yesterday.(注意:不规则动词如 go→went, have→had 等需单独记忆)
